To @ZZ whom t may concern.-

Beit known that I, JOHN I-I. PENDLEToN, of Brooklyn, in the county of Kings and State of New York, have invented an Improvement in Means for Picking Up and Dropping Gables in Cable Railways, of which the following is a specification.

ln cable railways, at their terminals and where one cable railway crosses another, it is io necessary to drop the cable by opening the grip, and the cable has to be again grasped at the proper place for connecting the car to the same.

My present invention is intended for performing the dropping and picking-up operations automatically, so that the car may pass an intersection by its momentum, and the picking-up mechanism will be made to operate between one stationary supporting-wheel upon zo the track and the next, and thereby not come int-o Contact with any portion of the cross-ties, track, or guide-wheels, and hand mechanism is also provided, so that the cable can be dropped or picked up with facility whenever required.

In the drawings, Figure 1 is a general plan view ofthe mechanism made use of below the ear, some of the hangers and bearings being in section. Fig. 2 is au elevation of the wheels 3o and grip at one side ot' the cable and a section of the parts that are directly over the cable. Fig. 3 is au elevation of one of the side shafts and a portion of the guardrail of the track. Fig. 4 is a crosssection showing the pickingup devices. Fig. 5 is a cross-section illustrating the manner in which the wheels act to receive and hold the cable, and Fig. 6 is a crosssection with the picking-up devices open, ready to be dropped for passing below and raising 4o the cable.

The crossties A., rails A', and guardrails A2 are of any ordinary character, and myimprovements are especially adapted to elevated railways and bridges.

Beneath the car there arehangers B, in pairs, to receive the rods or shafts B', from which are suspended the bearings or journal-boxes C', containing the shafts of the grooved wheels O, which are in pairs at opposite sides of the cable, as illustrated in Fig. l, and there are also gripping-blocks D, suspended by the stocks D' from'the shafts B', and these gri pping-blocks and the journal-boxes are fastened upon the shafts B', so that they can be swu n g toward the cable E or away from the same simultaneously, the shafts B forming the axis upon which the parts swing. In order to hold the wheels toward the cable, I make use of the shafts F in hangers F' from the under side of the car, and upon these shafts F are bent levers G, one end of each of which levers is hinged at 4 to the toggle-bar G2', and the other end ol' the togglebar is hingedat3toone of the journal-boxes C.

When the levers Gr are swung so that the joint 4 is raised, the bearings G are swung outwardly at their lower ends and the wheels C separated, so as to drop the cable, and upon the parts being moved in the opposite direetions the wheels C are brought against the cable. I prefer to make use of spri ngs H to bring the toggles into line, and thereby hold the wheels G toward each other. These springs may be of any suitable character. At the lower end of each bent lever G is a. roller, G7, to be acted upon by a stationary incline or cam, H', upon one of the guard-rails of the track, so that at the proper place upon the track the levers G will be moved and the ca` ble dropped.

In Fig. 1 I have shown four sets of bent levers and toggle-bars, two of these being adapted to act upon the rear pair of bearings and the other two upon the forward pair ot' bearings; but if the shafts F are extended, as indicated by dotted lines, the levers G may befastened permanently upon such shafts, and it will only be necessary to have rollers upon two of the bent levers for operating upon all four sets of togglebars and levers.

I have notshown any means foracting upon the positive gri ppingbloeks D to firmly clamp the cable by such blocks,as mechanism adapted to this object is well known and the same may be of any desired character.

When the bent levers and togglesbars are turned into the position shown by dotted lines in Fig. 5, they are kept in that positionby hanging hooks I upon the shafts l', that are supported in hangers I2, and these shafts are turned by mechanism hereinafter described,

so as to unhook the toggle-bars and allow the springs H to swing the bearings and wheels C up against the cable after the cable has been lifted.

The mechanism for picking up the cable is specially illustrated in Figs. 2, 4, and 6. The cross-shaft K is supported by the hangers K', and at one end is a crank-arm, L, and there is a second crank-arm, L', pivoted at the lower end of the outer hanger, K', and the rollerbar M is connected at the outer ends of these crank-arms, and it can rise and fall, as it is held vertically, or nearly so, and the crankarms are parallel as they swing, and at the lower end of this roller-bar M is a roller, y1., above cam-inclines N, that are upon the guardrails, or at the sides of them, and these caminclines are at the proper places and atk the proper inclinations, as illustrated in Fig. 2, to allow l[he picking-up devices to drop under the cable and then immediately to be raised for lifting up the cable.

The devices for picking up the cable are applied at front and back of the pairs of wheels 0, and these devices are similarly constructed, and it is hence only necessary to describe one of them. There is a second cross-shaft, K2, similar to the cross-shaft K, except that there is not any crank-arm L; but the two crossshafts K and K'l are provided with crankarms O, connected ttogether by the rod O', so that said shafts K and KZ move together, and one carries the forward picking-up devices andthe other the rear picking-up devices, which picking-up devices are alike. From the shafts K K2 the arms P extend, and at their outer ends is the cross-head P', with pivot ends passing into eyes at the ends of the arms P, and below the cross-head and formed with it is the fixed side Q of the pick-up, the

same being slotted vertically and having through it the guide-bar 10 at the lower ends of the curved arms 11 from the hangers K', so that this cross-head and fixed side of the pickup can be raised and lowered nearly vertically as the cross-shaft (K or K2) is partially turned in its hangers. The swinging side R of the pick-up is pivoted at 12 upon the cross-head P', and it is slotted vertically for the guidebar 10 to pass through, and there is a pin, 13, through the cross-head P' and Within segmental slots in R,to limit the swinging movement of this side R of the pick-up. Togglelinks S extend from the xed side Q to the swinging side R ofthe pick-up.

Upon one of thc arms 11, below the hanger K', a pawl, T, is pivoted at 14, and the upper end of this pawl is beneath one end of the head portion ofthe swinging side R of the pick-up.

It will now be apparent upon reference to Figs. 4 and 6 that when the pick-up is in the elevated position shown in Fig. 4 the liftingroller U at the lower end of the swinging side R is beneath the traction cable E; but if the shafts K K are partially turned, so that the arms P lower the cross-head P' to the position shown by full lines in Fig. 6, the pawl T will swing the side R into the position shown in said Fig. 6, and the cable will be unsupported, except by the wheels and grip, and the toggles S will be drawn so that their joint will be in line with each other, and the parts can remain in this position until the roller m runs down one of the cam-inclines N, and the shafts K K2 are still further turned, and the pick-up devices Q R are lowered and assume the position shown in dotted lines, Fig. 6, wherein the head of the swinging side R has slipped off the end of the pawl T, and the center of the toggle S has rested upon the stationary projecting pin 16 upon the arm 17, and been held up so that the lifting-roller U has swung in under the cable E, and the parts are in positions for lifting the cable by the roller m in running upon the cam-incline N, so that the cable is brought into position bctweenthe` pairs of wheels and the positive grip by the` pick-np devices acting in front and at the rear of such pairs of wheels previous to the said wheels and grip being brought toward each other to hold the cable.

I prefer to withdraw the pawl T automatically, so that after the cable has been liberated by the parts assuming the positions shown by full lines in Fig. G the pawl T may still hold the pick-up mechanism from descending farther, even though the roller m may not be in Contact with the cam-inclines N. To effect this object, the shaft c is supported in hangers V', and it is provided with a crank-arm, 20, and a connecting-rod, 21, to the pawl T, and the crank-arm 22 on said shaft V receives a roller-bar, XV, with a roller, 23, at the lower end, to be acted upon by an incline or cam,Y, upon one of the guard-rails of the track, so that at the proper place upon the track the cam will lift the roller 23 and bar W and turn the shaft V, and by the crank-arms 20 and connecting-rods 21 both pawls T will be simultaneously withdrawn, allowing the pick-up devices to drop and the lifting-roller'sU to pass in under the cable, and immediately thereafter the cam-'incline N acts to turn the shaft K K2 and lift the cable up into place.

Upon the shaft 1', before mentioned, there are arms 25, that extend out above the arms P, so that as the shaft K is turned and the arms P raised in picking up the cable the arms 25 will be acted upon and the shafts I partially turned, as illustrated in Fig. 5, to swing the hooks I from beneath the pins Gr4 upon the toggle-bars G, so that the springs 'H and toggie-bars swing the wheels C toward each other and grip the cable simultaneously with the picking up of the same.

In order to render it unnecessary to support the roller m, it is preferable for the parts to remain in the position shown by full lines in Fig. 6 so long as the car is being acted upon by the cable; hence when the cable is to be dropped it will only be necessary to separate the wheels C by the stationary i'nclines or cams H upon the guard-rails, and then when the cable is to be picked up the cam Yunlatches IOO IIO

the piek-np and allows the roller m to rest on the top of the incline N and roll down the same as the piek-np descends and the rollerU passes below the cable, and then the incline N immediately acts to lift the piek-up and cable, the wheels and grip next close upon the Cable, and then as the roller m passes off the incline N the piek-up is partially lowered and sustained by the pawl T in the position shown by full lines in Fig. 6.

lf a eliaiinOi, is connected to one part of the bar O', and the said chain passes to a shaft and the hand-Wheel, similar to a brake, then the pielvup can be operated by hand instead of by the incline N, and a chain, 28, passing over a roller, may extend from the erank-arn1 22 to a shaft and hand-wheel, so as to Withdraw the patri T by hand for dropping the pielmip, and it is preferable to wind up the chain 0 before withdrawing the pawl T, and then to lower the piek-up by unwinding the chain, and then to wind up suoli chain to raise the piek-up and cable.
